Organic Calla Mix

All 6 colors from the Bloemoloog® collection in one mix!
Many know it also by the name, 'calla lily', 'Zantedeschia' or 'arum lily.' The calla is a large-flowered plant with often broad, spotted leaves. In a pot, it reaches about 50 centimeters in height, while in the garden, it grows slightly taller, reaching a height of approximately 70 centimeters with larger flowers. Each tuber produces about 3-5 flowers per year and blooms from June to September.

Its flowers are actually leaves that curled up form a calyx, making the calla unique! The leaves are often spotted and also vary in shape. One type has narrow elongated leaves, while another type has broader leaves. Callas come in many colors. The vibrant color of the bract attracts insects that pollinate the flowers.

How, where, and when do I plant calla tubers?

The best location for a calla is in partial shade, where it blooms for months. Plant the tuber in nutrient-rich soil and ensure good drainage to prevent water accumulation around the tubers, which can lead to rot.

The calla tuber is formed by clusters of tubers. Sometimes green points are already visible, and it is easy to see what is above and below. If not, plant the tubers with the round side up and the flat side down. Cover the tuber with 5 to 10 centimeters of soil. The tuber develops roots at the top, so it needs some soil at the top of the tuber. Space them 10 centimeters apart. For container planting, they can be planted slightly closer together.

Indoor pre-growth

From March, the tubers can be pre-grown indoors. Water sparingly and move the plant outdoors on frost-free days.

Outdoor in the Garden

After the last frost, usually after the Ice Saints (May 15), the risk of frost is minimal, the tubers can be planted outdoors in the garden or in pots. Water the soil regularly to prevent it from drying out, but avoid excessive moisture, as it can cause the tubers to rot.

Tip: Plant the tubers in groups of at least three with a distance of about 15cm between them for a beautiful full result.

Care for organic calla

Remove faded flowers to stimulate new blooms. Hold the plant gently at the base to avoid accidentally pulling out the whole calla tuber.

After flowering, the plant naturally dies off. Let the leaves die off completely so that the energy returns to the tuber. Protect them from light frost in winter; they can tolerate no more than -10 degrees Celsius in the ground. In severe frost, they should be dug up and stored frost-free in a dry and cool place. The advantage of digging them up is that the tuber can be divided every year, as it gets larger each year.

For potted plants, we recommend storing the entire pot frost-free and not providing water in winter.


The calla originally comes from South Africa. The meaning of calla is 'beauty,' and it symbolizes purity, sympathy, and cleanliness. In Greek and Roman times, they mistook this flower for a chalice used for toasts, thus comparing the flowers to celebrations.
